Corner cases are were code reviews are really helpful! It's taken many years to separate "you should have done it how I would have done it" from "this code is ok to be merged". It's helpful to think "does this pr improve the code overall". 

Bugs will happen. Keeping the critical sats-related code separate from the rest, + CODEOWNERS will keep the critical sections safer while letting the rest change more quickly.

In some cases the code is fine but I suspect it could have uncaught corner cases or improved but I'm not 100% sure and I don't want to "alert" the author if I'm wrong.
